Abstract: A system can receive an indication associated with establishing a transmission control protocol (TCP) connection. The system can determine, based on the indication, information that identifies a user device associated with the TCP connection. The system can determine, based on the information that identifies the user device, a predicted congestion level of a base station associated with the TCP connection. The system can select, based on the predicted congestion level, a congestion control algorithm to be implemented for the TCP connection. The system can cause the TCP connection to be established and implement the congestion control algorithm for the TCP connection.

Abstract: A device can transmit, to a transmission control protocol (TCP) receiver, a quantity of packets based on a congestion window (CWND) value. The device can receive, from the TCP receiver, a quantity of acknowledgement (ACK) packets, that include a corresponding quantity of advertised receive window (RWND) values, based on transmitting the quantity of packets. The device can determine a maximum value for an updated CWND based on the CWND value and the corresponding quantity of RWND values. The device can provide a quantity of additional packets, to the TCP receiver, based on the maximum value for the updated CWND to cause the TCP receiver to selectively increase a size of a receive buffer.

Abstract: A device may determine one or more round-trip time threshold values and may determine a round-trip time value associated with a flow. The device may determine a smoothed round-trip time value based on the one or more round-trip time threshold values and the round-trip time value. The device may determine a congestion window threshold value based on the smoothed round-trip time value and may determine a congestion window value based on the congestion window threshold value. The device may provide traffic associated with the flow based on the congestion window value.

Abstract: A device can determine a congestion window (CWND) value, associated with a first transmission control protocol (TCP) state, for a TCP flow that involves one or more devices using active queue management (AQM). The first TCP state to cause the CWND value to be increased at a particular rate. The device can determine a round trip time (RTT) value, associated with the first TCP state, for the TCP flow. The device can determine that one or more TCP state conditions are satisfied. The device can classify the TCP flow into a different TCP state. The different TCP state to cause the CWND value to be maintained, decreased, or increased at a rate that is different than the particular rate. The device can transmit one or more packets, associated with the TCP flow, based on classifying the TCP flow into the different TCP state.

Abstract: Techniques for reducing network congestion are disclosed. In one embodiment, a method is disclosed comprising receiving, by a computing device, a packet from a sender over a network; retrieving, by the computing device, congestion information; inserting, by the computing device, congestion data representing the congestion information into a header option of the packet to generate an augmented packet; transmitting, by the computing device, the augmented packet to a receiver; receiving, by the computing device, a response packet, the response packet including the congestion data; and transmitting, by the computing device, the response packet to the sender.

Abstract: A device can determine a set of flow characteristics associated with an encrypted traffic flow. The set of flow characteristics can include a cumulative length of payload packets included in the encrypted traffic flow, an average payload length of the payload packets, and a throughput associated with the encrypted traffic flow. The device can determine, based on the set of flow characteristics, whether the encrypted traffic flow is likely to be a video traffic flow. The device can cause the encrypted traffic flow to be managed based on whether the encrypted traffic flow is likely to be a video traffic flow.

Abstract: A device may identify a proxy connection associated with a first device and a second device. An application buffer of the proxy connection may be associated with a first buffer size for at least one of the first device or the second device. The proxy connection may be associated with a video communication. The device may determine a set of parameters relating to the proxy connection. The device may determine a buffer allocation for the proxy connection based on the set of parameters. The device may perform an alteration to the application buffer of the proxy connection to cause the application buffer of the proxy connection to be associated with a second buffer size. The second buffer size may be different from the first buffer size.

Abstract: A device can receive, from a user device, a request associated with a data service that includes one or more service identifiers. The device can determine whether the data service is toll-free by providing, to a server, a validation request that includes the one or more service identifiers. The device can receive a response from the server that indicates that the user device is eligible to use the data service toll-free. The device can obtain an internet protocol (IP) address that is reserved for the data service by using a service identifier to search a data structure. The device can provide the IP address to the user device to allow the user device to use the IP address for a data session. Traffic flow for the data session can be received by another server that uses the IP address to update an account of an entity sponsoring the data service.

Abstract: A device can receive, from a user device, a transmission control protocol (TCP) synchronize (SYN) packet associated with a request to establish a TCP connection with a server device. The device can prevent a first TCP connection from being established between the device and the user device based on the TCP SYN packet. The device can cause a second TCP connection to be established between the device and the server device based on the TCP SYN packet and after preventing the first TCP connection from being established. The device can cause a third TCP connection to be established between the device and the user device after causing the second TCP connection to be established. The device can transfer network traffic between the user device and the server device based on the second TCP connection and the third TCP connection.
